When scheduling either an actual or a self-anointed VIP to come to your party and speak as a special guest, the thing you have to remember is they’re usually doing you a favor. In most cases there’s nothing that requires them to show up – and even less that forces them to have a speaking roll. Usually they do it because they think they might have something of interest to say to the other guests at your party.
When you start making their life difficult – like by changing the time they’re scheduled to speak approximately 347 times in three weeks, they become less inclined to do you this favor. In fact they might become downright belligerent and decide showing up for your party is just more of a pain in the ass than it’s worth.
So here’s the thing, if you have your heart set on having a very special guest make an appearance at your very special party, try to pretend, even if it’s just for this one moment, that you’re not the second coming of the Gang that Couldn’t Shoot Straight. It would make your life and theirs ever so much easier.
